Chimichurri Sauce

  • 1/2 cup red wine vinegar

  • 1/2 cup fresh cilantro finely chopped
  • 1/4 cup fresh flat-leaf parsley finely chopped
  • 3/4 cup extra-virgin olive oil

Grilled Flank Steak

  1. Marinate the steak using about 1/3 to 1/2 of the marinate for about 3 hours in the refrigerator and up to overnight. Store the remaining chimichurri sauce in an air-tight container at room temperature.

  2. Using a cast iron grill pan on high heat, sear on each side for about 3 minutes.

  3. After searing each side, turn off the heat and let the steak continue to cook for approximately 10 minutes, 5 minutes on each side. Using your meat thermometer, take the steak off the pan when it hits 130 degrees F for medium rare (140 for medium, 150 for well-done). For a flank steak, I highly recommend medium-rare. Anything else will be quite tough.

  4.  When the steak reaches the desired temperature, remove it from the pan and let it rest on a cutting board, cover with aluminum foil for about 8-10 minutes before slicing. Tip: Slice the steak at a downward, 45 degree angle to the cutting board, which will help tenderize the steak.
